nix/TopmetalSe-A-Low-Noise-Pixelated-Charge-Sensor
The TopmetalSe is a pixelated charge sensor in the Skywater 130nm process, designed for the Selena Neutrino experiment as an imager for rare nuclear processes in amorphous Selenium.

nix/TopmetalSe-DPS
The TopmetalSe is a pixelated charge sensor in the Skywater 130nm process, designed for the Selena Neutrino experiment as an imager for rare nuclear processes in amorphous Selenium.
The TopmetalSe-DPS is a prototype/upgrade of the TopmetalSe that was previously submitted for tapeout. We include a "digital pixel sensor," where we digitize the analog voltage within each pixel using an in-pixel ramp-adc.
We include multiple test structures, including individual digital pixels, small digital pixel arrays and independent ADCs.
